To all whomit may concern:

Be it known that I, CLARK Paulina, a

citizen of the United States of America,

and a resident, of Springfield, county of Hampdcn, and State ofMassachusetts, hat-e invented certain new and useful Improvements inControlling-Levr 'Mechanism,. of which the following is a specification,reference bein ing, forming a part thereof.

My invention relates to controlling lever mechanism of the type employedfor com trolling and operating transmission caring and the like, andconsists in improve means whereby a controlling and operating lever maybe connected atwill with any one of various ope 'ating elements, andprevented from being connected with other than the desired operating.elhment. when being so operated. p v

In carrying out my invention I employ one or more movable abutmentsmounted upon,-and car'ied by, the main operating and controllinglever,the same being con veniently operated by means of, a hand latch, thesaid abutment-s being adapted to connect with various operating arms inaccordance with the position of the said abutments upon the said mainoperating or controlling lever,-and I provide a guiding and limitingmeans for determining the position of the said abutments, the samecomprising a stationary quadrant having a peculiar form of openingtherein and provided with shoulders and abutments for el'lgaging aportion movable with the said abutments, all as will be readilycomprehci'ided by reference to the accompanying drawings and to thefollowing detailed description, and in order that my thoroughlyunderstood, I will now proceed to describe an embodiment thereof, havingreference to the accompanying drawings illustrating the same, and willthen pointoutthe novel features inclaims.

1n the drawingsz-Figure l-is a view in central transverse sectionthrough controlling means constructed in accordance with.

my invention. Fig. 2 is a transverse sectional view of certain of theparts, the plane of section being taken upon the line 22 of Fig. 1 Fig.3 is a view in vertical section upon the line 3--3 of Fig. 1.. thecontrolling ll-var and operating arms being shown in had to theaccompanying draw invention ma y be side elevation. Fig. 4; is a view invertical section upon the plane of the line l -t of Fig. 1. Figs. 5,hand 7 are detail views in side elevation of the operating arms. 'Fig. 8is a detail view in side elevation of the guiding and lockin quadrant.

The main controlling lever 10 is pivotally mounted a its lower end in aframe or casing 11in such a way that forward or rearward movements maybe imparted thereto, and pivoted co-incidentally therewith are threeoperating arms 12-l3-1t shown sepa-rately and in detail in Figs. 5, .6,and 7. The upper ends of the several levers 12-131t are provided withprojections arranged for co-engagementwith a movable element carried bythe said lever 10. This movable element comprises a slide 15 secared tothe controlling lever 10 by means of bolts 16-16, the'bolts passingthrough-air elongated slot in the said slide 15 whereby alimitedlongitudinal movement of the said lever with respect to thecontrolling lever 10 is permitted, and abutments 17 48 extendinglaterally of the said lever upon opposite sides of the said slide.'lhese abutments are arranged for (Io-engagement with the upperbifurcated ends of the operating arms 12-13 1-1, the abutment 18 beingarranged in the lowermost position 01 the slide for engagementwith theoperating arm 12, and in the uppermost position of the slide with theoperatil'lg arm 14:, while the abutment 17 arranged in an intcrn'lediateposition of the slide for engagement with the operating arm hen eitherof the aludments is so engaged the other arms are trolling lever andpivotallyconneeted at the end. opposite to that at which It isconnect-oi with the link to the said slide. \Vhen the latch 19 isdepressed the slide 15 will he lifted while when it is released a spring23 Secured-to the stationary casing 11 is a quadrant 24 having a guidingopening theretion and then to depress slots to the other.

in which tends to guide, limit, and determine the movement of the slidein the following -manner. This through a slotted portion of the slide 15and a pin 25 with which the said slide is provided and which passesacross the said slotted portion is received within a "aiding opening inthe said quadrant 24:. T1118 guiding opening comprises three slots26-27-28 arranged parallel with each other and concentric with thepivotal axis of'the lever, the three said'slots having progressivelyincreasing radii. -The said slots are separated by tongues 29 30, andcross-over passages 31-432 serve .as means by which the pin 25 may becaused to pass from one of the said The cross-over passage 32 isarranged Outof direct line with the cross-over passage 31, or, in otherwords, the tongue 30 is longer than the tongue 29 and extends across apath directly in line with the said cross-over passage 31. In the normalrest position of the parts the pin 25 lies upon the bot-tom.of thelowermost slot 26. In this position the lever may be moved freelybackward and forward without manipulation of the hand latch 19 in anymanner, and in this bered that the controll'iiig lever is connectedthrough the medium of the slide 15 and the abutment 18 with theoperating arm 12. I'Vhen it is desired to disconnect the controllinglever from engagement with the operating arm 12 and to connect it withthe operating arm 13 it: will be necessary to first bring thecontrolling lever to a central posithe latch 19. This 15 so as todisengage the the operating arm 12 and will lift the slide abutment 18from to cause the ahutnient'li' to engage with the operating arm 13. Theinner end'of the tongue 30 will act at this time as a lil'niting stop toprevent the pin from passing into the slot 28 so as to insure the properengagement of the abutment 17 with the operating arm 13 and to preventan accidental excess movement such as would cause the abutment. 18 toengage the arm .l-'l-. The controlling lever may now he given a backwardmovement. and will thereby transmit a-corresponding movement to the arm13 and a corresponding operation of the parts controlled and operatedthereby. I11 order to cause the locking pin to enter the slot 28 it willhe neeessauv utterit has been lifted to p a point where it is stopped bythe tongue -30, 'to more the controllin lever slightly forward, lie

- engagement with the tongue pin 2? from 30 and permitting, itto enterthe cross-over slot 32-, and thereafter upon a further depression oftlie thereby freeing t quadrant passes positionitwill be rcmemlatch 19the pin will be caused to pass around the endof the ton e 30 through thecross-over passage 32, emf thus into the slot 28. When inthe slot 28 thelever 10 may be moved backward to thereby impart an operating movementto the operating arm 14.

From the foregoing it will be seen that the various slots 26*27-28controlling the position of the slide 15 and hence of the portion orportions thereof will operatively en-e gage the various operating armsso that durmg an operating movement of theeontrol ling lever 1t will-beimpossible for the slide move with relation to the lever 10 even thoughthe latch 19 be released. In the neutral I tongue 30 will act to preventthe accidental central position of .the lever the overthrow movementofthe slide and will limit the movement of the slide to the proper degreeas is desired, while a complete upward movement of the slide is readilyeffected by a simple movement of the lever simultaneously. with theexertion of a slight force upon the hand latch 19.

The several operating arms 12-l3-14 may be connected with any suitablemeans such as the clutch mechanism of'transmission gearing, and in thedrawings I have shown them as secured to a plurality of coneentricshafts 33 34 and 35, the shafts 33 and 34- being hollow lid-surroundingthe shaft 35, and I have s llown'the main controlling lever 10 asconnected to a .hollow shaft 36'also disposed concentrically with theother said shafts and located between-the shafts 33 and 34. Theseveralshafts 33 34-35-36 are provided at their inner ends with arms37383940, the upper ends of which engage clutch operating .shipper rods41'42-4344. It is unnecessary in the present application. to go into thedetails of this clutch mechanism ,as the same forms no part of thepresent invention, but for the complete drawings and description of adevice with which. this controlling mechanism is adapted to be employedI refer to a copending application Serial Number 545,563
